SLIP-ON FLANGE SIGHT GLASS TYPE 393
SHORT DESCRIPTION - ROUND SIGHT GLASS DEVICE FOR INSTALLATION ON AN OPEN PIPE END
The ACI Slip-on flange sight glass Type 393 is a round sight glass device for installation on an open pipe end.
This simple sight glass device is instended for slip-on welding. The base flange is placed onto the pipe opening and welded according to the established rules. Onto this base flange, the inner gasket, the sight glass window, and the external glass cushioning are arranged and fixed using the cover flange.
Type 393 is equipped with borosilicate industrial glass according to DIN 7080, which resists most chemicals and high temperatures. If even this highly resilient glass is not sufficient for your application, we can protect it using additional mica discs, or replacing the borosilicate glass with quartz or sapphire glass.
As seal material we use proven flat gasket materials like KlingerSIL C4400 or Frenzelit novaphit MST. Elastic material like silicone, EPDM or NBR is likewise available.
As flange material, you can choose between high quality stainless steel like 1.4571 or 1.4404, duplex steel, established pressure equipment steel alloys like P265GH or S235JRG2 as well as high performance alloys like Hastelloy.
